| {4.1} Q 3: what are hybrids? | Hybrids are offspring's of different species . |
| {4.1} Q 4: what is the process of creating a hybrid called and what problems do they face? | The process of creating a hybrid is called hybridisation and the problems they face is health problems and in-fertilisation. |
| {4.1} Q 5: what is the science of classifying organisms known as ? | The science of classifying organisms is known as taxonomy. |
| {4.1} Q 6: what is the meaning of Linnaean classification? | The definition of Linnaean classification is A way of organising living things, In biology plants and animals have traditionally been classified by the structure of their bodies, in a descending hierarchy of categories: kingdom, class, order, family, genus, and species. |

| {4.1} Q 10: how do many scientists see evolution ? | Many early scientist saw evolution as an improvement of species resulting in increasingly complex species with humans being the most complex . |
| {4.1} Q 11: what influences whether a species becomes more or less complex ? | It depends on the characteristics the species needs in order to survive its environment. |
| {4.1} Q 12: who is Charles Darwin ? | English biologist whose scientific theory of evolution by natural selection became the foundation of modern evolutionary studies. |

| {4.1} Q 14: what is bio-geography ? | Bio-geography is the study of the distribution of species and ecosystems in geographic space . |
| {4.1} Q 15: who was Alfred Russel Wallace? | Alfred Russel Wallace was one of the leading biologists and explorers. He co-discovered with Charles Darwin the theory of evolution by natural selection, and he is one of the founders of the modern field of bio-geography. |
| {4.1} Q 16: what is artificial selection? | artificial selection is the breeding of plants and animals to produce desirable traits. |
| {4.1} Q 17: what is crossbreeding ? | known as producing an offspring particularly through mating two purebred individuals but from two different breeds . |
